Slide trumpet.

Technical description: Brass with silver mouthpiece receiver sheath, three-part ball and garland. The final 96mm of the bell flare is joined to the spout by a circumferential seam and has its own tabbed seam. The proximal yard (at the join between the mouthpipe and tuning-slide proximal leg) passes through t recess in the larger middle part of the ball. The proximal 320mm of the mouthpipe is set an an angle to the bell pipe (obviating th need for a curved bit). There are two alternative tuning-slides which pull towards the bell, the shorter for F and E?, the longer for E? and lower; the longer of these adds 206 to the sounding length and has its a short internal slide for D? allowing a combined further extension of up to 366mm; a longer internal slide gives D? C? and C?.The main slide it fitted for a tension spring return and has a maximum pull of 163mm (adding up to 326mm to the sounding length); a clamp with ligature screw restraint can be pre-set to limit the travel to any pull between 0 and 163mm; the screw also acts as a finger touchpiece for operating the slide. There are rubber ring buffers to cushion and silence the slide return. Each leg of the main slide and tuning slides has proximal inner and distal outer.; Nominal pitch: F etc.; Type or system: Webb model.; ; ; ; ;
